MONGOC_IOVEC_T(3)

okay bestie, welcome to MONGOC_IOVEC_T(3) from libmongoc 💖 this page is short but lowkey iconic, so let’s get into it.

✨ SYNOPSIS ✨

SYNOPSIS

here’s the exact shape of the thing, no cap:

#include <mongoc/mongoc.h>

#ifdef _WIN32
typedef struct {
   u_long iov_len;
   char *iov_base;
} mongoc_iovec_t;
#else
typedef struct iovec mongoc_iovec_t;
#endif

so the mongoc_iovec_t structure is literally a portability abstraction for consumers of the mongoc_stream_t interfaces. it allows for scatter/gather I/O through the socket subsystem. very main character behavior, honestly 🦋

WARNING: when writing portable code, beware of the ordering of iov_len and iov_base because they are different on various platforms. therefore, you should not use C initializers for initialization. like, do not do it, bestie 😭💀
